CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 334,355, dated January12,1886.

Application filed November 7, 1885. Serial No. 182,138.

To all whom it may concern.-

Be it known that I, MATHEW DILL, a citizen of the United States,residing at Piqua, in the county of Miami and State of Ohio, haveinvented certain new and useful Improvements in Car-Couplings; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to car-couplings; and it consists in the detailedconstruction and combination of the parts hereinafter fully de scribedand claimed.

In the drawings, Figure 1 is a side view of two couplings connectedtogether the positions of the coupling-hooks before engagement beingindicated by dotted lines. Fig. 2 is a plan view of the same. Fig. 3 isa side view of one coupling provided with a special link engaging with apin-andsocket coupling as ordinarily used. Fig. 4 is a plan view of thesame.

Similar letters of reference indicate corresponding parts in all thefigures.

A is the coupling-socket, one of l which is attached to each end of eachcar by any suitable arrangement of draw-bar and springs; o it may bebolted to the car.

Each socket A is provided with a vertical hole, a, and a vertical slot,to. A portion of the top of the socket is cut away at one end of thehole a, leaving the bar a of suitable form for the coupling-hook tocatch over.

Horizontal holes a are formed in the socket on each side of the verticalslot a, and short vertical slots a are formed at one end of the holes a,so that the pivots of the couplinghook may be inserted into the saidholes.

B is the coupling-hook, provided with pivots b, trip 11, and stop I).

O is a cover-plate, pivoted to the top of the socket by the pin 0, andprovided with a slot, 0, in which the coupling-hook works.

When the cars are approaching each other, the coupling-hooks stand, asshown by the dotted lines in Fig. l, with the stops 1)" resting upon thetop of the cover-plates. When the cars meet, the trip 12 of each hookstrikes against the end of the socket on the opposite car, and each hookfalls and catches over the bar a of the-opposite socket.

(No model.)

In order to uncouple the cars, they must be pushed together. The hookscan then be raised, using the trip'b for handles.

The cover-plate keeps each hook or link from coming out of thehorizontal holes in the socket.

WVben it is desired to couple a car provided with a socket, A, toanother car having a common pin-and-socket coupling, such as D, aspecial link, E, is used. The link E is open at one end, and is providedwith a pivot, e, and a hook, e. The coupling-hook B is re moved from thesocket by turning the coverplate on its pivot until the pivots bcan'pass out of the holes a through the slots a". The link E is theninserted in its place. The hook e of link E engages with the bar a whenthe pivot e is placed in the end of the hole a, and the looped portionof the link can then be coupled to the pin of the coupling D in theordinary manner. I

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

1. In a car coupling, the combination of a socket in the top of thedraw-head, a removable coupling hook or link having lateral bearings andpivoted in the said socket, and a cover-plate pivoted to the top of thedrawhead over said-socket and retaining the said hook or link within it,substantially as and for the purpose set forth.

2. In a car-coupling, the combination of the socket A, provided with theholes a and a the slots a and a and the bar a a coupling hook or linkpivoted in the said socket, and

a cover-plate pivoted to the top of the said socket and retaining thesaid hook or link within it, substantially as and for the purpose setforth.

3. In a car-coupling, the combination of the socket A, provided with theholes a and a the slots a and a, and the bar a the couplinghook B,provided with the pivots b, the trip b, and the stop b", and thecover-plate 0, provided with the pivot-pin c and slot 0, substantiallyas and for the purpose set forth.

In testimony whereof 'I affix my signature in presence of two witnesses.

MATHEW DILL.
